I also was able to A/B it with my SWR Gol. Jr.

The Box:

Immediately noticeable is that this is one big 2x10 and it pretty much dwarfs the Gol. Jr. There's just a lot more happening inside the Accugroove with its 3-way compartmentalized design. The good news is that it's almost exactly the same weight as the Jr. at ~55lbs. and isn't bad to carry at all. As long as you have a hatchback or something it should not be a problem. Construction is excellent and from the outside, appears at least on par with the best cabs such as Epifani. It looks cool.

Power Handling:

It will take a bunch. The cabinet allows 8/4 ohm impedence switching, and I was running it at 4 ohms with my 1602 bridged mono and the cabinet was taking volume at 50% without batting an eye.

Sound:

Obviously, the most important part. I should warn you that my expectations had been worked way up. I have to say I was not immediately blown away - let me explain. I was expecting to have my socks knocked off, but what I heard was, well, pretty much the sound of my bass. This cabinet doesn't offer "ear junk food" like SWR - which is two scoops from the middle - and this can sound pretty good in the living room.

The Accugroove is aptly name in that it's very accurate. Very balanced across the spectrum, very neutral and natural, but not sterile. At first I thought my SWR was putting out more low-end, but I realized that it was just the tuning of the SWR playing tricks on me. The SWR Jr. puts off a nice low grunt, but it really rolls off on the last few notes on the B. The Accugroove doesn't have "grunt" - but rather accurately produces the last few notes at the same volume as the rest of the notes on the bass.

At first I felt I was "missing" something while playing the fretted. And I was - coloration. It didn't take long for me to get used to hearing my bass. Slapping wasn't as aggressive, but was more even. Finger style notes were also more even, and less cluttered/muddy. The fretless created the biggest quality delta - with Accugroove you really get the nuance of every aural detail of every mwah.

The tweeter(s) on the Accugroove blows SWR away - no contest, but then again the SWR tweeter is pretty much a joke. Let me just say that the Accugroove tweeter(s) are among the best I've ever heard - balanced with rest of cabinet and no SWR-hiss. At least as good as Epifani.

In terms of volume, the Accugroove was the hands down winner. Not surprising considering its power handling and additional 6" speaker. Moreover, the Accugroove didn't break up at high volumes. It retained the even sound of my bass.

My thoughts:

Again, this cab is aptly named. It is really accurate even at high volumes. It's a bigger box, but it is probably all a player needs for all but the biggest gigs. It's solidly built and the weight is remarkable for its size.

It really all comes down to what you want from a cabinet. If you want to hear the sound of your bass accurately through the spectrum, and you want it in a single light package, this might be the cabinet for you. If you're hooked on "ear junk food", you might be left craving your aural fix. A colored cabinet can sound like it has more "balls" ..

Pros:

Solid box, highly accurate sound, accurate down to low B, good power handling, high volumes without breaking up, light weight, sweet tweeters, 4/8 ohm switch

Cons:

Aint cheap, big box (though light), need good power, if you like speaker coloration, this isn't for you
